ROCKLAND, Maine — The proposed methadone clinic for Rockland remains in need of at least one license before it can open for business.

Colonial Management LLC, through its local company Metro Treatment of Maine, received approval from the Rockland Planning Board in November to open the clinic at the former Turning Tide methadone clinic location on Route 1 by the Thomaston town line. The Rockland City Council had approved a zone change in September to allow for the clinic to operate at the site. The previous clinic has operated under a specialized zone agreement with the city.

Rockland’s code enforcement office had stated in January that the company planned to open by the end of that month.

Guy Cousins, the director of the Maine Office of Substance Abuse, said Friday that the application by Metro Treatment was still pending before the Maine Department of Health and Human Services. He said the Maine Board of Pharmacy had approved a license for the company.

Special Agent Anthony Pettigrew of the U.S. Drug Enforcement Administration said April 20 he was not sure if the DEA had issued a federal license but said he would check into it. No further information has been provided.

A telephone message was left Friday morning with Joe Sullivan of Colonial Management. He has not responded.

The company’s plan calls for serving up to 400 patients with opiate addictions at the Rockland facility. Turning Tide had served about 200 patients.
